2016 Boletín de Investigaciones Marinas y Costeras  
In these assemblages, the trophic and taxonomic structure is more affected by the spatial variation in the physical characteristics of the water column and sediment than by the seasonal variation.  ...  The polychaete abundances at family level and their trophic mechanisms were used for this purpose. Sediment samples were collected at six stations in this bay during the wet and dry seasons.  ...  ecosystems in Bahia de Portete", requested and fully funded by the company Carbones del Cerrejón, LLC, as part of its environment protection programs.  ...

Seasonal, Interannual, and Spatial Variability in the Concentrations of Total Suspended Solids in a Degraded Coastal Wetland of Lake Ontario

Patricia Chow-Fraser
1999 Journal of Great Lakes research  
Interannual variation in TSS concentrations was inversely related to mean seasonal water levels that fluctuated 45 cm over the 11 years.  ...  The overall temporal and spatial distribution of TSS in the marsh reflected changes in water level, wind activities, onset of rain events, and fish disturbance that acted in concert to keep Cootes Paradise  ...  These photos were arranged to derive a composite of the entire marsh for each flight. The composites were digitized and have been computer enhanced for presentation in this paper.  ...
